How to Choose the Optimal CPAP Battery for Camping Adventures

If you rely on CPAP therapy but still enjoy the outdoors, having a portable power solution is key. When selecting a battery, consider crucial factors like capacity, weight, versatility, features, durability and warranty.

Capacity

Look for a battery rated to fully charge your CPAP machine at least once, if not twice, before needing a recharge. The EXP48PRO will power your CPAP for a minimum of 2-3 nights. Check our our CPAP runtime calculator to see exactly how long each battery model will run your CPAP machine. Account for at least 3 hours more than you need for your trip. This provides a safety buffer in case of unexpected higher power needs. Lithium batteries tend to offer higher energy densities than heavy lead-acid options, packing more power into a compact size. 

Safety 

Batteries with LiFePO4 chemistry, such as the EXP96PRO, are exceedingly safe compared to other lithium types like Lithium Ion. LiFePO4 batteries have high thermal stability and will not catch fire even if punctured or overcharged. This peace of mind is important when camping in remote areas, or when using pass-through charging on your nightstand.

Weight & Size

Consider how you plan to camp - whether car camping where weight isn't a concern, or backpacking into remote areas. Heftier batteries may be acceptable for a vehicle but go as light as reasonably possible for hiking long distances with gear. The EXP48PRO is an optimal size and weight for backpacking. Battery shape and included accessories also impact overall packability. If you're car or RV camping, opt for the EXP240PRO. This battery will give you all the ports and power that you need. In addition, this battery model can make use of higher solar charge currents like that produced by our EXP PRO Summit 100 Solar Panel.

Versatility

In addition to powering just your CPAP, look for a battery that allows simultaneous charging of other essential devices like phones, GPS units or headlamps via USB or DC ports. This provides flexibility. All our battery models also integrate solar charging capabilities, allowing you to recharge off-grid using sunlight for true independence on extended trips.

Durability

Choose a battery with an all-weather design proven to withstand dusty, wet, hot and cold outdoor conditions over multiple seasons. Lithium-ion chemistries maintain their charge better when not fully discharged between uses, versus lead-acid alternatives. Look for impact resistance and water-resistant casing ratings to feel confident about reliability in remote areas.

Warranty

Quality batteries always include long warranty periods, commonly 2 years or more. This protects your investment and gives peace of mind that the manufacturer will stand behind their product, even replacing it if anything goes wrong during multi-day trips in remote locales far from home.

Doing thorough research upfront makes finding the ideal camping companion battery for keeping CPAP therapy uninterrupted under the stars achievable and hassle-free.
